I have had 2 problems over the years that may come close to yours. Is the check engine light is on?
1. The torque converter lockup solenoid is defective causing it to remain stuck locked. When you stop
in this condition it would start bucking like a bronco and you then need to throw it into neutral to avoid stalling.
Cure: replace torque converter lockup solenoid
2. Transmission is stuck in high gear and did not automatically shift back down to 1st gear when you come to a stop. This would not buck like a bronco but takeoff will be very poor because the trans is stuck in high gear.
Try shifting into low and see if the problem is cleared. This was similar to yours also in that it took a while for it
to warm up enough to happen.
Cure: this was under warranty and they replaced the valve body.
